The film earned Academy Award nods for Best Picture and Best Director.The husky-voiced starlet went on to star in the popular sitcom One Day At A Time (1975-1984) as a rebellious teen opposite Valerie Bertinelli as her younger sister and Bonnie Franklin as their groundbreaking, for the time, single mom.Casting a dark cloud over her career bright spots was the fact that Phillips is also the daughter of troubled singer-songwriter John Phillips, founder of The Mamas and the Papas. It's veteran TV and film star Mackenzie Phillips. Phillips is seen in the role that made her a star at 12, Carol Morrison in George Lucas' American Graffiti Phillips starred as a tomboy teen opposite a gruff-but-caring hot rodder played by Paul LeMatShe alleged in her haunting 2009 memoir High on Arrival that she had an incestuous sexual relationship with her late father for 10 years, beginning when he raped her at 19, on the night before her wedding to first husband Jeff Sessler.Her bombshell revelation not only rocked the public, but divided her family. Phillips became pregnant, but had an abortion after not being sure whether the baby belonged to her California Dreamin' dad or her spouse, who had no idea about the secret abuse.Phillips once considered the relationship 'consensual,' but through treatment came to realize she was a victim, not a participant, as detailed in a two-part appearance on her former co-star's Valerie's Place podcast in October 2026.'I learned from my [2009] appearance on Oprah and my book that – because I was calling it consensual because I was trying to protect him – there is no such thing as consent between a parent and a child,' she told Bertinelli. 'The power differential is too great.'In June 2026, Phillips revealed some additional drug-fueled debauchery that went down behind-the-scenes with Bertinelli on their family-friendly CBS sitcom.The pair played sisters Julie and Barbara Cooper on the series, but Phillips struggled with substance abuse and was fired twice from the show.Phillips recalled how they would unwind from the set with wine and cocaine. Phillips, then 19, with her One Day at a Time co-stars Valerie Bertinelli, Bonnie Franklin and Pat Harrington in 1979 when her character got married; struggling with addiction, she would be fired from the Norman Lear sitcom for the first time the next year Phillips in one of her many TV guest star spots, this time a 1980 episode of The Love BoatPhillips in one of her many TV guest star spots, this time in a 1980 episode of The Love Boat'So this might surprise you that during lunch break, Valerie and I would drive to my house, get in the pool, drink wine, and snort coke,' she told Fox News Digital at the Chiller Theatre Expo, a popular fan convention in Parsippany, New Jersey.She added what she was sharing was nothing new and stressed she was the one struggling with substance abuse, not Bertinelli.'But Valerie talks about it openly, so it’s not like I’m pulling her covers or anything,' she said. 'The thing was that I was the, you know, Valerie didn’t have the kind of addiction that I had, she didn’t have addiction.' 'And you know, so we would do coke together in the dressing room and stuff,' she said. 'I just happened to be the one that got caught. And thank God I got caught, you know?' Bertinelli admitted in October 2026 that she was a teenager when she first tried cocaine with Phillips, as reported on Today.The drug use continued into her relationship with her ex-husband, the late Eddie Van Halen.'The priest we tapped to perform the ceremony gave us questionnaires so he could get to know us better and offer more personal words. As we filled out the forms at home, we each held a little vial of coke,' she recalled in her 2008 memoir, Losing It.'It doesn't really bode well for the marriage, I don't think,' she added.

Phillips with her second ex-husband, Michael Barakan, better known as English rock guitarist Shane Fontayne, whose worked with artists such as Bruce Springsteen, Graham Nash and Joe Cocker, among others.During her interview with Chynna, she also reflected on when she was fired from One Day At A Time.'My addiction was so powerful and so out of control that when I was fired for the second time from the show for drug use, I thought, "Ah screw them, you know, I'll get my next job in a minute," that did not happen. And I became basically unhirable for a long, long time,' Phillips said.'Once I got sober for the first time I realized that I had to put my pride in my back pocket and not go, "Well I was on the biggest TV show of all time," because there were many like me who refused to audition and I just said you know what I'm putting that behind me, and I went out and I pounded the pavement and I auditioned against a bunch of other young women and I started booking gigs and I started booking jobs.'I was sort of in episodic hell for a long time and then the Disney Channel show [So Weird] came along... it was a great show, it was so much fun.'She appeared in 65 episodes of So Weird from 1999 to 2001 but didn't land another major role again until Orange Is The New Black (2018) and Netflix's One Day At A Time reboot (2017-2020).In 2008, Phillips pleaded guilty to possessing cocaine after she was arrested at Los Angeles International Airport earlier that year.It was alleged she was 'carrying what appeared to be heroin and cocaine in baggies and balloons,' according to airport police, Reuters reported. Due to severe addiction to cocaine and heroin, arriving late, and being incoherent on set, Phillips was fired from the hit sitcom in February 1980 at the age of 20 As part of her plea deal, Phillips agreed to complete an 18-month drug treatment program, according to Fox News.Now Phillips, who came out as bisexual at 62 in 2022, has turned her life around and uses her own past struggles to help those battling addiction.The star has since become an addiction counselor at the LA treatment facility Breathe Life Healing Centers.'My addiction was so powerful, and so rooted in early trauma, that I lost myself for many years,' she says on their website. 'Now, with a strong recovery I’m committed to helping others find their voice at Breathe Life Healing Centers.'
